Azerbaijani President Ilham Aliyev has been re-elected for a fourth term.

Final results of the election released Thursday by the Central Election Commission showed that Aliyev had won with 86 percent of the vote, well ahead of seven other candidates in the race for office.

The commission has put the turnout at 74.5 percent.

The crushing victory comes amid allegations of vote-rigging by main opposition parties. The opposition Republican Alternative Movement, one of the main parties that had boycotted the election, has denounced the vote as a sham to have Aliyev re-elected.

“All previous elections in Azerbaijan were falsified and held with blatant violations of the electoral law. These elections will be no exception,” said Natig Jafarli, who serves as the party’s executive secretary, ahead of the vote.

The opposition was also angry about a decision by Aliyev’s administration to hold the election six months ahead of schedule. They said the decision, which they called surprise and unexplained, was meant to shorten the campaign period and hamper efforts to stop vote-rigging.

Authorities rejected the criticism and said the vote was completely free and fair.
